Whenever I'm browsing something heavy or torrenting, my router has a habit of losing connectivity and requiring powercycle. For example, on the penny-arcade forums, there are many threads in the art section that have many pictures per page. My router will often die when these start to load, and all computers on the network lose connectivity. When I'm getting something like the Diggnation videopodcast (legal) via bittorrent, when I get a decent number of connections and transfers, the router will die, or it will die when I stop seeding the video. So, I'm wondering if it is indeed my router (almost positive), and what, if anything, I can do to resolve this issue. Below is any info I thought was relavant. Thanks in advance for your help.

---WEP 64 bit
---UPnP enabled, period 30 min, TTL 4 hops
---Port Fowarding for range used by bittorrent

Computers:
---#1: PC Hardwired to router via cat5, WindowsME
---#2: Laptop Wireless (B standard), WindowsXP SP2
---#3: PC Wireless (G standard), Windows XP SP2 and Kubuntu Linux "Breezy" (dual boot)

Browser: Mozilla Firefox, pipeline enabled, max request lowered from 8 to 6 in attempt to fix

If you need any other info, let me know. Thanks again.

Hi BoomShake007,

Please goto Start, Run, type EVENTVWR, press 'OK'. Now look under the System logs for any TCP/IP warnings. If you find a warning, open it up by double clicking on it; is the warning the same as this:
TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.
If so, please download this Patcher (the english version; top link). Run it (choose to increase the limit to 50). Then restart your computer. Test your connection.

If that did not help, then does your router lose any power when the computers lose their connectivity? Are all of the relevant lights flashing, etc?

Can you regain a connection by going to Start, Run, type CMD, press 'OK'. Now type:

• ipconfig /release -- wait for the connection to release; then
• ipconfig /renew -- wait for the connection to re-establish, or alternatively for an error message to display -- if it is an error message, please post the message.

no TCP/IP problem reported. I read about how SP2 breaks the TCP/IP stack thing in XP, although I don't believe this is the problem here.

this time a release/renew did work on the wired pc. usually it doesn't reconnect. all lights are on.

In my experimentation, I think I may have found atleast part of the problem. Firefox's pipelining. I had it on, set to 8 max requests. On the thread that usually kills things with it's many decent sized images, it did as planed, and died. However, I turned pipelining off, cleared cache, and went to the page and other pages with many images, and things stayed working. I really hope the router isn't that weak that it can't handle something like pipelining.

I also read that in some of the other versions of the WGR614 router, overheating of the router's cpu was a problem, and that sticking a penny or quarter on the chip helped with the cooling and solved a lot of folk's disconnect problems.

To test if it is a router issue, I'd suggest plugging one computer directly into your modem and then attempting to browse that website -- does it still lose connectivity?

In that case, do your computers still lose connectivity at all?

I highly doubt your router would be "that weak".

I have never used FireFox before; what is 'pipelining'? What is it intended to do?

basically, instead of making one request to the website at a time, pipelining lets you do multiple ones simultaneously, up to 8.

and no, when i'm using firefox without the pipelining, i haven't had problems for hours. When i used it and went to those art pages, it crashed almost every time, even when done on different computers in the network.

i'll try a direct connect tomorrow if I have time.
